nie'n 2 a cmpiate Within cha-nne shown] w t cam by providing a groovedportion in which the other PI'OJGClTlOIl may be slipped. When thusassembled a half-turn in one direction serves to close a puncturedopening and wedge the seal and pourer, andahalf turn in the oppositedirection serves to wedge the members with the vent open. a

The vent-formed for egress of the fluid is through a punctured opening 9in the sealing member 3 and a registering opening 9 in the pouringmember 4. If desired an air-inlet opening 10 maybe formed in saidpouring member and a registering-opening 10 made in the sealing memberwhen a filled and closed container is to be vented. When the pouring andair-inlet openings have been made the liquid may be poured from thecontainer in quantities as great or as small as may be desired,and-after-such pouring any drip will remainin the cupped closure andtend to flow back into thecontainer during the time the apertures in thetwo members are in registration. VVhen the necessary amount of liquidhasbeen poured the container is closed by'turning the pouring member 4in its seat in thesealingmember 3, this serving to carry the openings inthe seal and pourer out of register and making of the pourer a shieldfor the openings in the seal. To wedge the faces of the two members moreclosely together the turning movement of the pourer on its seat may becontinued until the projections 5 arecarried into the cam grooves 8, inwhich position of the parts the punctured apertures in the seal will beeffectually closed.

In Fig. 4 I have shown a modified form of closure or seal provided withinterior vertical channels, such as 11, for receiving the guiding studs5 of a pouring member as before described, and these studs may then bedirected downward to the annular guideway 6, or the seal and pouringmember may be held together and wedged in any other de-.

sired manner.

In Figs. 5 andfi form of the device before described which has inaddition a filler 12 ofcompressible material carri-ed by the underfifaeeof the pouring member for contacuwith the upper face of the sealingmember 3. Tl'llS compressible material maybe attachedto' the pourer inany desired manner, but is shown herein as engaged by struck-up por'tions of the body of the pouring member. This compressible filleris'intended to pro.-

vide a more perfect seal against leakage than is possible when the metalsurfaces contact there is shown a modified directly, even underpressure. When the member 4 has been turned after pouring has beeneffected the aperturesin "the members 3 and 4 pass out of register, andupon the studs 5 entering the cam portions of the runway of the sealingmember, the compressible pad is pressed against the face of the sealingmember to effect more perfect sealing ofthe container. The air-inlet andliq- '"u1d-pour1ng apertures in the compressible member 12 aredesignated by 13 and 14 respectively.

Fig. 7 shows a sealing member 3 essen: tially as before described havingcam guiding members 15 on its inner surface adapted to co-operate with apouring member shown in Fig.8, the wedge cams 16, coacting with the cam15 to wedge the two members together in pouring position or in closedposition, as desired. A compressible stopper-17 is inserted in themember4 and serves to close the opening 10 made in the member 3 for pouringpurposes. A depressed runway pressed into the bottom of the memher 3 isillustrated at 18 in'which the under portion of the stopper '17 maytravel during that part of its movement when it is beingturned from itsposition of compression in open position to compression in closedposition in order to reduce friction.

Figs..9 andlO illustrate a modification in which the sealing member 3 iscupped and has internal guides for co-operation with a pouring member,whichjis here shown as a disc 22 adapted to be placed in and movedwithinsaid sealinglmember and'guided by members 23 formed duringassemblage. As

in other forms of my device pouring and air inlet openings 9 and 10 areshown in said disc, and the sealing member beneath SK-1d discv may bepunctured in registration with these openings to provide pouring andairinlet openings in the container. It Will be obvious, however, thatthe air-inlet opening inthis, as. in other forms of closure herein, maybe made at any suitable point outside the closure.

In all the embodiments of my device havingv relatively movable sealingand pouringmembers these are so combined as not to be subject toseparation except when; expressly manipulated for that purpose, and

adapted for radial movement within the sealing member, it will beobvious that such member may be so formed and applied as to move backand forth within said sealing member to cover and uncover, and to wedgethe two members in open or in close' position.

What I claim is:

1. In combination with a container having an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, apouring element, and positioning means for said pouring element to forcesaid element into sealing contact with said member in either pouring orclosed position.

2. In combination with a container having an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, apouring element carried in said closing member, and positioning meansfor said pouring element to force said element into sealing contact withsaid member upon rotation ofsaid element in either direction.

8. In combination with a container having an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, apouring elementheld and movable in said closing member, and positioningmeans for said pouring element to force said element into sealingcontact with said member in either pouring or closed position.

4. In combination with a containerliaving an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, anelement carried by said member and having a pouring opening,compressible means between said member and element, and positioningmeans for said pouring element adapted to force said element toward saidmember to compress said compressible means and to effect sealing contactin any one of a number of positions.

5. In combination with a container having an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, avent opening, an element carried by said member and having a pouringopening and a vent opening therein, and positioning means for saidpouring element to force said element into sealing contact with saidmember in either pouring or closed position.

6. A closure for liquid containers, comprising a sealing portion adaptedto be perforated to form a pouring opening, a pouring member movablyheld therein, and positioning means for said pouring member to hold saidmember in sealing contact .ith said sealing portion in either pouring orclosed position.

7. A closure for liquid containers, comprising a sealing member adaptedto be perforated to form a pouring opening, a pouring member held androtatable in said sealing member, compressible means carried by saldpouring member, and positioning means for said pouring member to forceit toward said compressible means to ffect sealing contact with saidsealing member in either open or closed position.

8. In combination with a container having an opening, a cupped memberclosing said opening and adapted to be perforated to form a pouringopening, a pouring ele ment, and positioning means adapted ,to hold saidelement in contact with said member in any one of a number of positions.

9. In combination with a container having an opening, a member closingsaid open ing and adapted to be perforated to form a pouring opening, apouring element, and positioning means adapted to hold said element incontact with said member in any one of a number of positions.

10. In combination with a container having an opening, a member closingsaid opening and adapted to be perforated to form a pouring opening, avent opening, a. pouring element, pouring and vent openings in saidelement, and positioning means to hold said element in contact with saidclosing member to seal said member in either open or closed position.
